2 Claims. (01. 20 -1'2 The invention relates to improvements in windowconstructions, and has for its primary object the provision of animproved construction of this character so constructed and arranged asto permit of the ready removal of the window sashes when desired.

Another object of the invention is the provision of an improvedconstruction of the character indicated so constructed and arranged asto prevent rattling of the window while in use.

Another object of the invention is the provision of a construction ofthe character indicated so constructed and arranged as to be practicallywater and wind tight.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by refer ence to the accompanyingdrawings forming a part of this specification, and in which Fig. l is apartial interior face view of a window construction embodying theinvention;

Fig. 2 a transverse section of the same taken through the sill of thewindow;

Fig. 3 a transverse section taken through the head jamb of the window;

Fig. i an enlarged horizontal section taken throughone side of thewindow frame; and

Fig. 5 asimilar section taken through the opposite side thereof.

The embodiment of the invention illustrated in the drawings comprises asuitable window frame constructed and arranged to be inserted in thewall of a building in the usual way and having a permanent jamb 10 atone side provided with the usual moldings and strips 11, 12 and 13,providing the usual pair of adjacent guide grooves for the window sashes14, this part of the construction being the ordinary, normal windowframe construction.

At its opposite side the window frame is provided with a vertical sideor anchoring jamb 15 secured as shown between vertical frame strips 16and 1'7. A laterally slidable jamb 2 is arranged to slide laterallybetween the vertical frame strips 16 and 17, said jamb 2 being providedwith moldings and strips 18 and 19, providing as shown the usual guidegrooves for the window sashes 14. The slidable jamb 2 is yieldinglypressed into sliding engagement with the sashes 14 by means of threecompression springs 1, each compression spring fitting over acorresponding positioning block 7 and fitting into a correspondingpositioning socket 9, whereby each spring is properly held in place toperform its function of yieldingly and evenly pressing the jamb 2 intoslidable engagement with the window sashes.

Guide strips 5 are arranged as shown on each jamb 10 and 2 substantiallyat the center of each sash groove, and each sash is provided on eachside with a corresponding guide groove as shown to fit the correspondingguide strip. Each sash groove is provided at each end with a bearingblock 4 adapted and arranged to ride upon the corresponding strip 5 andthereby confining the pressure to the four corners of each sash to pre-'vent binding when raising or lowering the same. For this purpose, eachof the blocks 4 is preferably made of fiber composition.

A guide block 6 is arranged on the window sill in position to contactwith the outer edge of the bottom of the slidable jamb 2 when it emergesfrom behind the strip 16, so that when the sashes are removed from thewindow the slidable jamb 2 will be held in place. A guide strip 6 isalso provided on the head jamb of the window frame, as best shown inFig. 3, there being a corresponding groove formed in the top of theouter sash to act as a weather strip and guide when the outer sash is inits uppermost position.

A suitable chamier or notch 8 is provided at the lower inner edge of thestrip 1'7, as indicated by the dotted lines in Fig. 4, to permit of thedraining of any water entering the pocket in which the slidable jambslides.

By this arrangement, it will be noted that the sashes can be removedwithout interfering with or removing the parting strip or any of theguide strips or moldings of the window frame by bringing pressure tobear upon the top and bottom of the slidable jamb, thereby springingsaidslidable jamb back far enough to permit of the ready removal of thesashes. As will be noted, the slidable jamb is at one side only so thatthe other jamb is the same as in any standard win dow frameconstruction. The construction thus provided will not shake or rattle inuse, and when the window sashes are closed, is practically air and windtight. As indicated, no sash cords or sash weightsare required for saidsashes.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails disclosed, but desire to avail myself of such variations andmodifications as fall within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. A window construction comprising a frame having a jamb at one sideprovided with two adjacent guide grooves for window sashes; a laterallyslidable jamb at the other side also provided with two adjacent guidegrooves for said sashes; a plurality of positioning blocks on thevertical medial line of the outer side of said slidable jamb;compression springs engaging such positioning blocks and the adjacentframe sides, there being sockets in said frame sides registering withsaid blocks to receive the ends of said springs; a guide strip on eachjamb substantially at the center of each of said guide grooves, therebeing corresponding guide grooves in said sashes to receive said strips;bearing blocks at each end of the guide grooves in said groove for awindow sash; a laterally slidable spring-held jamb at the other sidealso provided with a guide groove for said sash; a guide strip on eachjamb substantially at the center of each of said guide grooves, therebeing corresponding guide grooves in said sashes to receive said strips;and bearing blocks at each end of the guide grooves in said sashes tocontact with said strips.
